I discovered a few days a ago that I made an error in making the Search Plugins of the GNOME Amazon Store. I put an extra dash into the affiliate id: gnome-searchplugin vs gnomesearchplugin. Hence all the items you bought via the search plugin did not result in affiliate fees for the GNOME foundation :-(.
As the affiliate center of Amazon by default shows an aggregate of all affiliate ids of the GNOME foundation I didn’t notice it until a few days ago. Because I was surprised about that the affiliate fees were not going up I decided to look into it and discovered that the search plugins did not register any clicks or sales. I’ve now updated the plugins and these register the clicks. So please remove the ones you have currently installed and install the new ones listed below or on http://www.gnome.org/friends/amazon. Sorry about the mistake but the good news is that the GNOME Foundation can probably get much more value out of the affiliate fees in 2010.
Please drop me a line when you bought something with the plugin. That way I can make sure that they work correctly now
